Description

[0029] Further advantages and features of the invention will become apparent from the following description of preferred embodiments and the drawings to which reference is made. These should not be understood in a limiting sense. In the drawings:

[0030] FIG. 1 shows a fire protection element according to the invention within a wall that has a formwork;

[0031] FIG. 2 shows the fire protection element from FIG. 1 within a wall;

[0032] FIG. 3 shows the fire protection element from FIG. 2 after it has been moved out of the wall; and

[0033] FIG. 4 shows an alternative embodiment of the fire protection element in a ceiling.

[0034] FIG. 1 shows a fire protection element 10 according to the invention, which is fastened within a formwork 12. The fire protection element 10 comprises a cladding pipe 14, a movement device 16 and a fire protection insert 18. In addition, the fire protection element 10 has a continuous opening 20 in the cladding pipe 14. The fire protection insert 18 is arranged so as to be movable in the longitudinal direction of the opening 20 in the cladding pipe 14.

[0035] The movement device 16 can be coupled to the fire protection insert 18 such that the fire protection insert 18 can be moved together with the movement device 16 from a starting position in which the fire protection insert 18 is located within the opening 20 into an end position in which the fire protection insert 18 is located at least partially outside of the opening 20.

[0036] At the same time, FIG. 1 shows a freshly cast concrete wall 22, of which the size and shape is predetermined by the formwork 12. An opening is created within the wall through the cladding pipe 14 of the fire protection element 10 and through the opening 20 of the fire protection element 10 at the same time.

[0037] The wall 22 can, as shown in FIG. 1, be cast vertically in a vertical formwork 12, but can in principle be cast lying in a horizontally oriented formwork 12 as well. The fire protection element 10 ends flush with the wall 22.

[0038] FIG. 2 illustrates the wall 22 shown in FIG. 1, in which wall the fire protection element 10 has been cast. In addition, a combustible body 24, in this case a pipe 25, has been passed through the opening 20 of the fire protection element 10. The fire protection element 10 ends flush with the wall 22 as before.

[0039] In a next step, the fire protection insert 18 can be moved out of the wall 22 by means of the movement device 16 so that at least part of the fire protection insert 18 lies in a collar-like manner in front of the wall 22, as shown in FIG. 3, and encompasses the combustible body 24.

[0040] In this case, the movement device 16, for example, can have a thread which engages in a matching mating thread, for example on the cladding pipe 14, thus allowing the movement device 16 to rotate out of the wall 22, for example by hand or by means of a suitable screwing tool. Instead of the thread, one or more guiding grooves can also be provided in which corresponding guiding pins or ribs engage. As a result, the fire protection insert 18 is also at least partially moved in front of the wall 22 together with the movement device 16.

[0041] FIG. 4 shows an alternative embodiment in which a fire protection element 10 has been cast in a ceiling 26. In this embodiment, a fire protection insert 18 and a movement device 16 are provided only on the downward-facing side of the ceiling 26. On the upper side of the ceiling 26, the cladding pipe 14 ends flush with the ceiling 26. The opening 20 of the fire protection element 10 is therefore predetermined on the lower side of the ceiling 26 by the fire protection insert 18 and on the top of the ceiling 26 by the cladding pipe 14.

[0042] In the shown embodiments, the fire protection insert 18 is directly connected to the movement device 16. According to a further embodiment, at one or at both axial ends of the fire protection element 10, a receiving space (not shown) can be provided in which the movement device 16 and/or the fire protection insert 18 are received. In this way, the movement device 16 and the fire protection insert 18 can be separate from one another. For example, the movement device 16 can comprise a spring element which acts on the fire protection insert 18 and moves said insert into the end position in front of the wall or ceiling as soon as a counterforce exerted by the formwork 12 or a retaining apparatus is eliminated.

[0043] The illustrated fire protection insert 18 can comprise, for example, expandable graphite or another intumescent material as the fire protection material 28. In this case, the expanding intumescent material closes the opening 20 in the event of a fire as soon as the combustible body 24, here the pipe 25, melts.
